i have a difficult time determining my true weight. I have been weighing myself several times a day for the past 6mo and noticed how much my weight fluctuates. of course its due to whatever is in my stomach at the time (after dinner I can weight 5 lbs more than before or after a long ride I can loose 10+lbs of water etc) Perhaps the best way to get an consistently measurable weight would be to make sure my stomach is empty and after a moderate ride? My nutritionist also has a bioimpedance meter that measures lean body mass and fat mass which I consider a better metric than overall body weight. less water = less lean body mass
